Abstract
Problems in measuring eye movements are briefly reviewed and a simple, inexpensive technique is presented for counting either the number of small eye movements during fixation or the number of small plus large eye movements during visual search. Details are given for building the system, which reflects infra-red light from the corneal-scleral margin of the eye to a photocell. The methods of operation and analysis of data are presented and the strengths and weaknesses of the technique are summarized. Examples of its use in particular experiments are presented.
